Hrmm,.. this is growing to be very large indeed.
It would be nice to know where all these extra entries are coming from. How large are:
# cat /proc/lockdep | grep -v -e "\->" -e "^$" | wc -l 437
# cat /proc/lockdep | grep -v -e "\->" -e "^$" | awk '{print $6}' | tr -d ".:" | grep -v "^$" | wc -c 1031
On your machine?
